Detailed explanation-1: -Oxidation involves loss of electrons and reduction involves gain of electrons.

Detailed explanation-2: -Oxidation is the loss of electrons, gain of oxygen or loss of hydrogen. Reduction is the gain of electrons, loss of oxygen or gain of hydrogen.

Detailed explanation-3: -Oxidation–reduction reactions, commonly known as redox reactions, are reactions that involve the transfer of electrons from one species to another. The species that loses electrons is said to be oxidized, while the species that gains electrons is said to be reduced.

Detailed explanation-4: -Assertion :Oxidation involves loss of electrons and reduction involves gain of electrons.

Detailed explanation-5: -Reduction is defined in terms of gain of electrons, loss of oxygen, gain of hydrogen, or a decrease in oxidation number. Oxidation and reduction always occur together, even though they can be written as separate chemical equations.
